tresdin has just created a new issue for
https://github.com/w3c/webrtc-pc:
== Automatically open data channel when connections are established ==
I personally think data channel should be opened by default.
Developers should not handle this task themselves. There are not much
reasons to open a webrtc connection without using the data channel.
And also, after connections are established, webrtc should handle
itself every renegotiations via the default data channel.
